. A further object is to provide a flight and link construction for achain conveyor adapted to operate over flat and sloping surfaces formingthe 'pan'of the conveyor. v

' A still further object is to provide a flight and link constructionfor a chain conveyor having a pin composed of contiguous sections someof which are flat and others of which slope angularly from the chain,which is so constructed that the flights .will engage all sections ofthe pan regardless of whether the section is flat or sloping.

These and other objects which will hereinafter those skilled in thisparticular art, are accomplished bymeans of this invention. oneembodiment of which is described in the following specification andillustrated in the accompanying drawing wherein:

Fig. l is a plan View of a flight and linkconnector for a chain conveyormade in accordance with my present invention. 1

Fig. 2 is a view in end elevation of my flight and link connection, andFig. 3 is a section takenon Fig. 1.

- In the drawing, in which like numbers of references designate likeparts in all the figures, l represents a conventional roller link chaincomposed of a series of block lin'k sections 2 connected together byside straps 3.

line 11m n of improved In practicing my invention, the straps 3 at fregularly spaced intervals throughout the length through the legs of"the channel section 5 beveled or undercut as of the chain l arereplacedv with a connector link 4. having a central inverted channelshaped straddle the ends 2'. Pins 6 extend and adjacent links 2' to theconsection 5 which is adapted to of adjacent roller block links securethe ends of necto'r linkAl- I Projecting outwardly from each side of thechannel section 5' of the link 4" is a lug T which extends betweenthelegs 8 of abifurcated flight 9. The legs Bof'the flight 9" arepivotally secured to thel'ug -1 by a pin lflwhich extends throughregistering openings in the legs 8' and. the lug 1 and are arranged tobe parallel to the channel section 5 of the connector link 4.

The undersides of the legs 8 of each flight are at l l to provide arelatively small end [2 on each leg of the flight adjacent the uppersurface thereof which is adapted to abut against or engage that portionof the outer surface of the channel section 5 located above the pin l0.

From this construction it is apparent that since the legs 8 only engagethe connector link 4 at a point above the pin 10, the flight 9 is freeto turn from a horizontal position to a downwardly sloping position fromthe connector link 4 but cannot extend upwardly above such plane since'conveyor and since the flights are prevented from turning above ahorizontal plane, the raising of the flights from engagement with theconveyor pan as they pass from a downwardly sloped portion to ahorizontal-portion contiguous therewith is prevented.

What I claim as new and desire to secure by Letters Patent is: x

I 1. In a chain conveyor, the combination comprising a chain and flightsprojecting outwardly from the opposite flights having a for attachingsaid flight to said chain, and means Thus the connection the chainthereby increasing the material handling capacity of the side of saidchain, each of said bifurcated end to provide legs for pivotallyconnecting said legs to said chain, each of said legs having itsbottomedge thereof cut away to provide a relatively narrow end for abuttingagainst said chain above said pivot, whereby said flight is free toslope downwardly from said chain but movement thereof above a horizontalplane is prevented.

2. In a chain conveyor, the combination comprising a block link chain, aconnector link for joining the ends of adjacent block links of saidchain, and a flight pivotally connected to each side of from each sideof said channel section, and a flight pivoted to each of said lugs andabutting against the side of said channel section, each of said flightshaving a beveled corner on its inner end to permit turning movementthereof in one direction.

4. In a chain conveyor, the combination comprising a connector link,having a central chanits bottom corner beveled to permit downwardturning movement thereof.

5. In a chain conveyor, the combination comprising a connector link,having a central channel section pivotally connecting the ends ofaddirection.

6. In a chain conveyor, the combination with a k link chain, comprisinga connector having a channel section for receiving the ends of adjacentblock links and to which said links are pivoted, a lug projectingoutwardly from each side flight pivotally connected to each of saidlugs, each of said flights having a end, providing legs adapted tostraddle its respective lu said lugs having the upper corners on theinner ends abutting against the sides of said connector, and a beveledbottom corner to permit downward turning movement of said flights.
